Description

  The present invention relates to an underfloor storage part structure in which an upper floor is provided so as to have an inner space height of 140 cm or less from a floor inside a room space of a residential building and a storage part is formed in a lower part of the upper floor.

  In recent years, in order to effectively utilize the limited room space in a residential building, the lower part of the room space is used as a normal living space, and the part up to the ceiling above the living space is used as a loft. Various floor plans are adopted. The loft has an inner space height of, for example, 140 cm or less above the area used as a living space having an inner height of 210 cm or more from the floor surface in the room space. It is used as a simple sleeping space or storage space without being included in the floor area.

  On the other hand, the loft needs to be supported above the floor surface while maintaining a height for the living space below it. However, if a dedicated support structure such as a support beam is provided, it is not possible. Since it becomes economical, various simple support structures for efficiently supporting the loft have been proposed (see, for example, Patent Document 1 and Patent Document 2).

In addition, the loft is provided above the living space that occupies a considerable height, and when used as a simple sleeping space or storage space, it is troublesome to go up and down from the floor via stairs or ladders. Therefore, as a new proposal, it is conceivable to provide a simple space that is not included in the floor area in place of the loft in the room space, for example, below the living space as a storage unit.
